Top 10 Best New Chat Software of 2026

Mattermost supports on-premises and self-hosted deployments, which matters when data residency and controlled rollouts restrict SaaS adoption. Channel permissions and RBAC controls manage who can read, post, and moderate across workspaces, teams, and channels. The platform also exposes automation hooks such as incoming and outgoing webhooks and a documented REST API for building custom automations. Message search and scoped settings help teams keep conversation history usable for support workflows and internal investigations.

A key tradeoff is that adopting external integrations and bot workflows requires additional configuration compared with lighter SaaS chat setups. Mattermost fits teams that need conversation retention controls and admin governance for long-lived collaboration in regulated environments, especially when SSO and audit logs are required for access reviews.

Discord uses a server-based hierarchy with channels and permissions tied to roles, which maps well to internal teams and community programs. Threads and message history provide continuity for collaboration, and voice rooms support real-time work alongside text. Extensibility comes from bots, webhooks, and app integrations that can trigger actions from messages or events.

A key tradeoff is that Discord is not built as a standardized omnichannel contact center, so conversation routing and unified inbox workflows require extra design. Discord works well when teams want agent-like teamwork in a shared workspace, such as triaging user questions in dedicated channels and running structured bot responses. It is less suitable when teams require strict governance around enterprise help desk concepts like agent work queues and centralized omnichannel reporting.

Chanty centers on workspace management for teams that need consistent conversation ownership, clear context, and repeatable responses. The app provides chat features like threads, mentions, and macros for faster replies, plus transcript visibility so teams can audit what was said and when. Automation rules can route conversations and enforce workflow steps when messages match conditions.

A key tradeoff is that deeper enterprise governance and compliance features can require careful configuration to match RBAC expectations and external tooling. Chanty fits when customer messaging teams want predictable routing and workflow steps without building a custom chat orchestration layer.

Slack is a team chat system with deep third-party integration and long-lived channels built for day-to-day collaboration. It provides searchable conversation history, threaded discussions, and a large apps ecosystem that connects chat to tools like ticketing, docs, and internal systems.

Slack also supports automation and extensibility through bots, workflows, and an API surface aimed at connecting external services to messages, users, and events. Strong admin and governance controls help organizations manage access through SSO, identity policies, and audit visibility across workspaces.

Microsoft Teams delivers group chat and threaded conversations inside workspaces tied to Microsoft 365 identities. The chat experience connects with Office documents, recurring meeting workflows, and app integrations across the Teams client.

Message compliance, retention, and supervision are handled through Microsoft 365 security and compliance tooling. Administration centers on tenant-level policies, user and role management, and activity auditing for governance.

Rocket.Chat fits teams that need self-hosted team chat with admin control and real-time collaboration. It combines channels and direct messaging with an automation layer for workflows, bots, and message routing.

System administrators get configuration controls that cover user access, data retention behavior, and extensibility via apps and integrations. Rocket.Chat also provides API-driven development for connecting external systems to conversation events and message actions.

Element brings encrypted team chat through a Matrix-based architecture that supports federation and long-lived conversation records. The app focuses on room-based collaboration, with flexible message history and moderation controls tied to each room.

Integrations are typically delivered through Matrix bridges and webhooks, which lets teams connect chat events to external systems. Automation is available through client and server capabilities that expose events for routing, handling, and audit-friendly operations.

Zulip organizes team chat around topic-based threads rather than a single scrolling timeline, which makes long-running discussions easier to search and resume. Messages can be grouped under multiple streams with optional topic names, and threads maintain conversation context inside a single workspace.

Admins can manage users, authentication, and stream governance, while integrations and automation hooks support external workflows. It is a fit for teams that want structured chat history and consistent routing of work across groups.

Pumble provides team chat with shared inbox-style collaboration for support and internal routing. The workspace supports assignments, conversation handoffs, and thread-level context so agents can keep customer context without exporting data.

Admins can manage users and SSO for organization access, while teams can extend chat workflows with REST APIs and webhooks. Automation covers routing, tagging, and message handling patterns that fit omnichannel customer messaging and live chat workflows.

Flock is a team chat product built around a browser-first experience and threaded conversations. It includes shared content areas for teams to keep project updates, files, and searchable discussion history in one place.

The product focuses on conversation organization and day-to-day collaboration rather than heavy contact-center automation. For teams evaluating chat options against Twilio Conversations and other developer-first messaging APIs, Flock leans toward workspace workflows instead of custom messaging pipelines.
